These are the following steps for No Thought Meditation,

• Sit in Sidhhansan. Hands on knees, eyes closed.
• Perform simple Vivekananda pranayama, or Anulom Vilom. for 10-15 counts.
• Do not move, be still, focus just on NOTHING. No thoughts, no imagination, simple just be.

You may start feeling some energies near sahastrara, or top of your head.
